A new block named 'data1' cannot be added

I am using for loop to create workspace variable block and conveter block and connect it.

While reaching at add block it gives error A new block named 'data1' cannot be added.

data =__ % defined in column

sys='testModel';

add_block('built-in/FromWorkspace',[sys, char(data(i))],'Position',pos1);

Most likely it is because a block with the same name already exists. Use the 'MakeNameUnique', 'on' option.

[sys, char(data(i))] is probably not right. Don't you want 'testModel/Data1' with the '/' seperator?

'testModel/Data1'
